但是,如果您只想在Linux中搜索某些文本的文件,则可以使用grep&＃xff1a;
burhan&＃64;sandbox:~$grep "Harry Potter" file.xml
Harry Potter
如果要搜索文件,请使用上面的grep命令,或打开文件并在Python中搜索它&＃xff1a;
>>> import re
>>> exp &＃61; re.compile(r&＃39;<.>&＃39;)
>>> with open(&＃39;file.xml&＃39;) as f:
... lines &＃61; &＃39;&＃39;.join(line for line in f.readlines())
... text_only &＃61; exp.sub(&＃39;&＃39;,lines).strip()
...
>>> if &＃39;Harry Potter&＃39; in text_only:
... print &＃39;It exists&＃39;
... else:
... print &＃39;It does not&＃39;
...
